Stirling Electric

[@sierraecho884]

Awesome, love it. This is exactly what I had in mind the stirling engine is very efficient while the electric motor is also very efficient but very powerful as well. Range extender stirling engine, awesome. And how quiet the boat is.

Thank you. It's taken a few years to get to the current state - but I now have a day boat for use - not an engineering project in development!

I'm doing a scaled up version of this right now.

Tell us more?.... Andrew

Hi Andrew, very good video and well explained. Are you using a charge controller of some sort? Kind regards

[@andrewhall2702]

Yes - The ePropulsion outboard can use 1kW at 48v DC. There is a battery, 48v, between the Stirling and the outboard. The outboard can use a little more than 20A at 48v (20A x 48v = 960W). The battery is rated to take charge, up to 25A, from the generator and also able to discharge at the same rate So, the generated current flows into the battery and straight out the other side If the generator is putting out 20A and the outboard is set to half speed then the excess is used to charge the battery The reverse also happens. The final piece of the "jigsaw" is that the Stirling produces AC. A Victron unit us used to covert to DC Have a look at kzbin.info/www/bejne/iKqQfGyunJx7m8U Andrew [e-mail]

@@andrewhall2702 thank you for an in depth reply. Is there something that limits the current from the stirling engine when the outboard is on full power? Or does the charge controller take care of this when the voltage drops? Sorry for all the questions : ) cheers

@@ShanePomeroy Always happy to answer questions. I think that the output from the Stirling engine is controlled by the Stirling engine control unit. The Microgen Stirling Power Cell (SPC) is used most widely as a combined heat and power unit. So the SPC is carefully controlled to produce 50 cycle AC at 230v - to feed the grid. Keep asking:) We will find the limits to my knowledge! Have a look at www.microgen-engine.com/

Still hoping to get my hands on a stirling motor powered by wood, just think, I could travel thousands of miles for months on end if I wished as the rivers have massive amounts of timber each side of them, simply load up each morning. I am on the Darling River, New South Wales.
